Nursing Elites

1. What are the expected findings in a patient experiencing hypokalemia?

• A. Flattened T waves on an ECG
• B. Elevated ST segments
• C. Prominent U waves
• D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.

2. A healthcare provider is assessing a client who reports a possible exposure to HIV. Which of the following findings should the healthcare provider identify as an early manifestation of HIV infection?

• A. Stomatitis
• B. Fatigue
• C. Wasting syndrome
• D. Lipodystrophy

Correct answer: B

Rationale: The correct answer is 'B: Fatigue.' Early manifestations of HIV infection often include symptoms like fatigue, fever, and rash, which are typical of viral infections. Stomatitis (choice A) refers to inflammation of the mouth and lips, which can occur in HIV but is not specific to early infection. Wasting syndrome (choice C) and lipodystrophy (choice D) are more commonly associated with later stages of HIV infection rather than early manifestations.

3. A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?

• A. It delivers a preset amount of inspiratory pressure throughout the breathing cycle
• B. It has a continuous adjustment feature that changes the airway pressure throughout the cycle
• C. It delivers a preset amount of airway pressure throughout the breathing cycle
• D. It delivers positive pressure at the end of each breath

Correct answer: C

Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

4. What intervention should the nurse take for a patient experiencing delayed wound healing?

• A. Monitor serum albumin levels
• B. Apply a dry dressing
• C. Administer antibiotics
• D. Change the wound dressing every 8 hours

Correct answer: A

Rationale: Monitoring serum albumin levels is crucial for patients with delayed wound healing. Low albumin levels indicate a lack of protein, which can impair the healing process and increase the risk of infection. By monitoring serum albumin levels, the nurse can assess the patient's nutritional status and make necessary interventions to promote wound healing. Applying a dry dressing (Choice B) may be appropriate depending on the wound characteristics, but it does not address the underlying cause of delayed healing. Administering antibiotics (Choice C) is not the first-line intervention for delayed wound healing unless there is an active infection present. Changing the wound dressing every 8 hours (Choice D) may lead to excessive disruption of the wound bed and hinder the healing process.

5. A nurse misreads a blood glucose level and administers excess insulin. What should the nurse monitor for?

• A. Monitor for hyperglycemia
• B. Monitor for hypoglycemia
• C. Administer glucose IV
• D. Monitor for increased thirst

Correct answer: B

Rationale: The correct answer is to monitor for hypoglycemia. Excess insulin can lead to low blood glucose levels, causing hypoglycemia. Symptoms of hypoglycemia include sweating, trembling, dizziness, confusion, and in severe cases, loss of consciousness. Options A, C, and D are incorrect because administering excess insulin would not lead to hyperglycemia or increased thirst, and administering glucose IV would exacerbate the issue by further lowering blood glucose levels.
